At 326 pixels per inch (iPhone 4) you need to hold a phone 10.5 inches from your face to see a pixel, assuming your vision is 20/20. In other words, at 12 inches or farther from your face, these displays are perfectly clear.

At 460 pixels per inch (rumoured Samsung Galaxy S 3 display), you need to hold that phone 7.5 inches from your face to see a pixel. How much reading do you do at such a distance? I think your optometrist would strongly recommend against reading something less than a foot from your face.

Now consider that a 1080p display will require around twice the computing power to render as the Galaxy Nexus' 720p display. Do you want your GPU to be working twice as hard at all times (and getting half the framerate for games and animations) for greater clarity in those moments when you hold your phone so close to your face that you go crosseyed?

Same arguement is why do TVs need more than 1080p since you can't visually tell a difference any more? Its that all that is important?

You can't stop improving just because its good enough.

Improvements in that clarity and density provide more in depth and visual appeal for movies and video in motion etc. CPU and GPU will continue to double regardless if the screen advances or not. As it all pushes forward it also breaks out of its prime market to advance other markets.

Games pushing computers to advance so quickly have lead to what we have now in home PCs. Phones pushing limits now will assist the battery industry into improving technologies which in turn help electric cars and other products. Likewise, improving the OLED screens in these samsung screens improve the tech overall wich will result in larger OLED TVs coming out quicker at reduced costs.

The difference is that you don't need to charge TV's. Phones consume a lot of power already and there is no advancement in battery technology. What you are saying is that they will sacrifice all that computing power for something that you won't be able to see and you will get a much less battery life. It is nonsense. Of course they can do it, companies make stupid decisions all the time.

Samsung doesn't produce experimental devices to improve other areas of technology. They are producing functional devices.
